6L.9

a) Write balanced half-reactions for the redox reaction of an acidified solution of potassium permanganate and iron(II) chloride.
b) Write the balanced equation for the cell reaction and devise a galvanic cell to study the reaction (write its cell diagram)

For this reaction, how do you determine which half-reactions to use? Thanks!

So usually spectator ions are not included in the half reactions, so in this case, the half reactions would contain one with manganese and the other with iron (potassium and chloride are not included). You then balance each half reaction, and then balance the electrons so that you can add them together and get the net reaction. I noticed that you posted a lot of questions on Chemistry Community, so if you need any further help, please go to peer learning sessions, TA OH, or Dr. Lavelle's OH. Thanks!
